Heather O’Sullivan, MS, RN, AGNP, a leading expert in health care innovation and transformation, is President of Healthcare at Home at Mass General Brigham, where she leads operations of one of the country’s largest Home Hospitals.

With three decades of experience, Heather has unrivaled knowledge and insight on strategic innovation and rapid growth initiatives in clinical and payer spaces. Under her leadership, Mass General Brigham’s patients receive the same, best-in-class acute-level hospital services as those at the system’s nationally recognized medical centers — but from the comfort of their homes. Since January of 2022, MGB Home Hospital has cared for over 2,500 patients, including over 1,500 in 2023 alone. The team’s patient-centered approach, technological investments and strategic partnerships have lowered mortality rates, reduced readmission rates and decreased patients’ length of stay, while reducing strain on hospitals and lowering the cost of care. Most recently, Heather spearheaded a novel, cross-sector partnership with Best Buy Health that will forge technological solutions, define, and optimize care delivery across the continuum of needs in the home setting, and create opportunities to enable the next generation of Healthcare at Home workforce. These accomplishments contributed to Heather being recognized as a Top Innovator of the Year by Modern Healthcare in 2023.

Within the $18 billion not-for-profit health system, Heather also manages a dynamic portfolio of affiliated at-home clinical offerings, including Palliative Care, Emergency services, and a Mobile Integrated Health fleet.

Prior to joining Mass General Brigham, Heather served as the Executive Vice President and Chief Clinical Innovation Officer of Kindred at Home, the largest home health and hospice services provider in the United States, during the period leading up to the Humana acquisition. Additionally, she previously served as Chief Clinical Officer at naviHealth and began her leadership journey at UnitedHealth Group, where she directed medical and clinical operations for full-risk health plans in the post-acute and community settings.
